To an whom it mag concern: 1 7

Be it known that I, LOUIS H. MARTELL, a citizen of the United States,residing atWil kinsburg,in the county of Allegheny and State ofPennsylvania, have invented or discovered certain new and usefulImprovements in Boxes for Packing-Rings, of which improvements thefollowing is a specification.

The invention described herein relates to certain improvements in boxesfor holding in operative position packing-rings for pistonrods of thetype or class forming the subjectmatter of an application, Serial No.121,431, filed by me August 29, 1902.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification,Figure .1 is a seetional view showing my improved box in position on acylinder-head and the packingrings in place in the box. Fig. 2 is a sideelevation of the box, and Fig. 3 is a plan view of the box.

In the practice of my invention the box is made in two or more sections,adapted to be united by bolts 2 passing through flanges 3, formed at theends of the sections. The box is provided with ribs 4, two, three, ormore in number, parallel with the axis of the box and having holes.the'rethrough for the passage of the studs or bolts 5, whereby the boxis'seoured to the cylinder-head.

: In the inner wall of the box are formed grooves 6 for the reception ofthe packingrings 8. It. has heretofore been customary to makethe' wallsof packing-boxes of this type comparatively thick, so that they wouldnot be seriously weakened by the grooves 6 and the holes for theSecuring bolts or studs 5. By my improved construction-z' e., formingribs 4 thereonthe box is strengthened and braced, that thev wallsthereof may be made comparatively thin. The box is further bracedbyflanges 9, arranged intermediate of the ends of the box and in a planeat right angles to theaxis of the box.

I claim herein as my invention- A box for packing-rings formed insections and provided with hollow external ribs and connecting flangesand having internal grooves for the reception of packing-rings,substantially as set forth.
